Cascadoss International Symposium and Workshop, 16th, 2008 - Jun 19th, 2008 in Warsaw, Poland

The international symposium will bring together both professional developers and (potential) customers of GIS/RS Open Source technology and will, as such, stimulate research & innovation and networking in this field. The workshop part targets GIS-experts with a high level of expertise in GIS and/or programming, such as software service providers and IT/GIS-SMEs.

Event organized within the CASCADOSS project.

Presentation: Trends in development of Free and Open Source Software for Geomatics (draft material)

  • Why-FOSS4G Trends:
    • The geospatial industry is moving toward Open Standards. Open Standards facilitates:
      • Interoperability between agencies which increases availability of data (in Europe, see INSPIRE)
      • Move to Standards based, Commercial Off The Shelf (SCOTS) software. In turn SCOTS software becomes a commodity item which brings the price of the SCOTS software down.
      • Without vendor lock-in traps, Open Source successfully competes with proprietary software.
  • FOSS4G Interoperability Trends:
  • FOSS4G WebGIS Trends:
    • Web 1.0: static pages ...
    • Web(GIS) 1.5: a bit dynamic pages
    • Web(GIS) 2.0: the "I GIS" Web
      • collective intelligence, crowdsourcing, collective mapping (OSM, ...)
      • GIS meets social Web
      • you and me with GPS: mapping party (new fashion in Italy)
      • Sensor web (SOS)
      • NASA WorldWind, ...
      • Mapserver (p.mapper, ka-maps, ...), OpenLayers, FeatureServer, Geoserver, MapGuide OS, pyWPS...
      • it's all about protocols and mashups
    • Web(GIS) 3.0: the semantic Web or the Geoweb (?)
      • our online data get (spatially) organized?
  • FOSS4G GIS Analytics Trends:
    • also (Desktop) GIS wants to be online: Web Processing Service (pyWPS, 52°N, ...)
    • federated databases
    • GRASS as free GIS backbone
    • distributed and parallel computing (GIS number crunching)
  • FOSS4G Community Trends:
    • Communication technology:
      • 80s: phone, letter, magnetic tape...
      • 1989 (?): GRASS FTP server online - the first FOSS4G GIS server in civil internet?
      • 1991: GRASS Mailing lists started: grass-user and grass-dev
      • Usenet comes up, interfaced with GRASS-MLs
      • 1994 (?): Web is invented - First GRASS Web site (CERL) - see GRASS Web site evolution
      • 1999: established, hosting PROJ, GDAL, OSSIM, libgeotiff, ...
      • 2000: mailing list and portal launched - fundamental for community building
      • 200x: Blogs, Wikis, emails (TODO: number of subscribers in all OSGeo lists; only in GRASS lists >4000), Voip, ... communication is easy
    • National FOSS4G corporations:
    • Conferences:
      • Many GRASS conferences since 80s in USA and Europe, drop in 1995, in Asia Bangkok 2004
      • Mapserver conference 2005
      • Lausanne 2006: Merge of Mapserver, GRASS, EOGEO conferences to FOSS4G conference series, then Canada 2007, now South Africa 2008, next Sydney 2009, ...
      • Annual national conferences:
        • in Italy annual conf since 1999 (first GRASS, now
        • in Germany annual conf since 2005 (first Mapserver, now
        • in Spain: gvSIG conf since 2007 (?)
  • FOSS4G Release Management and Quality Assessment Trends:
    • Code Management
      • 80's: GRASS source code is managed manually by the core developers (hey, no civil internet yet!)
      • 12/1999: one day before Year 2000, GRASS CVS is started (GDAL, Mapserver - no idea)
      • 2007: integrated OSGeo development platform: SVN, trac, wiki, mailing lists, IRC bots, buildbots
    • Release Management
      • till 2006 (?): separated, ad-hoc releases by the individual teams
      • since 2006: attempts to synchronize releases for common feature support etc.
      • since 200x: thorough test cycles with alpha, beta, release candidates (milestones in trac)
      • cross platform tests before releasing (code becomes portable: Linux, MacOSX, MS-Windows, ...)
      • aim: deliver end user product (also requested by now large user communities and distro packagers)
    • Quality Assessment:
      • Implementation of Code submission standards for C, Shell scripts, Tcl/Tk, and Python
      • 2006: GRASS Code Quality Control System started (currently under rewrite to open up for other OSGeo projects)
      • various scientific papers on this
      • supports clone detection and software engineering measures on code style
  • FOSS4G Documentation Trends:
    • 80's started with tutorials
    • 2002: Open Source GIS: A GRASS GIS Approach - first FOSS4G book ever
    • 2004 (?): first FOSS4G Wikis come up
    • 2006: OSGeo Education and Curriculum Committee is formed
    • 2007: FOSS4G primer and other book-like initiatives
    • 2008: Many FOSS4G books now available: bookshelf
  • FOSS4G Business Trends:
    • OSGeo Service Providers directory (almost 100 registered)
      • TODO: check covered countries, statistics per continent
      • TODO: check public tenders for open source, anyone having stats?
    • FOSS4G business model - [:Category:Advocacy|Category:Advocacy]
    • Provide commercial training directly as OSGeo brand? - ongoing discussion...
    • From Dave Mcllhagga's presentation on FOSS4G 2008:
      • value is the solution, not the technology
      • solutions drive the technology - not the other way around
      • FOSSGIS Business Models
      • Commercial (don't mix this up!) Proprietary GI solutions versus FOSS4G
      • hence FOSS4G == commercial
